Time frame
Every 8 weeks until disease progression up to the data cut-off date of 30 September 2008; Maximum follow-up time was 109 weeks.

What was measured

Duration of response was calculated only for those participants with a confirmed CR or PR, as the time from the first CR or PR (subsequently confirmed within no less than 4 weeks) to first observed disease progression per modified RECIST criteria, based on a blinded central review.

Groups in this outcome

Wild-type KRAS - FOLFOX + Panitumumab

Participants with wild-type KRAS were randomized to panitumumab, 6 mg/kg on Day 1 and FOLFOX chemotherapy regimen on Days 1 and 2 of each 14-day cycle until disease progression or unacceptable toxicity.

Wild-type KRAS - FOLFOX

Participants with wild-type KRAS were randomized to FOLFOX chemotherapy regimen on Days 1 and 2 of each 14-day cycle until disease progression or until unacceptable toxicity.

Mutant KRAS - FOLFOX + Panitumumab

Participants with mutant KRAS were randomized to panitumumab, 6 mg/kg on Day 1 and FOLFOX chemotherapy regimen on Days 1 and 2 of each 14-day cycle until disease progression or unacceptable toxicity.

Mutant KRAS - FOLFOX

Participants with mutant KRAS were randomized to FOLFOX chemotherapy regimen on Days 1 and 2 of each 14-day cycle until disease progression or until unacceptable toxicity.
